\ FLOOR-PLANER.

Specification of Letters Patent.

Patented June 25, 1907.

Application filed February 9,1907. Serial No. 356,501.

To all whom it may concern.-

Be it known that I, CHARLES T. LEIMBAOH, a citizen of the United States, residing at Oatonsville, in the county of Baltimore and State of Maryland, have invented. certain new and useful Improvements in Floor-Planers,

of which the following is a specification.

My invention relates to an improvement in planing machines as applicable to and for the purpose of planing, smoothing and cleaning hard wood floors and the like, where a smooth uniform surface is required.

With the foregoing object in view, my invention consists of certain new and novel features of construction and combinations of parts, which will be herein after described and pointed out in the claims.

I do hereby declare the following to be a full and exact description of my device, such as will enable others skilled in the art to which it appertains to make and use the same.

Referring to the drawings, Figure 1, is a longitudinal sectional view with parts broken away so as to show the invention to a better advantage. Fig. 2, is a plan view of the complete machine; Fig. 3 is a detail view of the tension device Fig. 4, is an inverted plan view of the cutter head; Fig. 5, is a detail view of the cutter blade.

A is the frame, made of any suitable inaterial (preferably cast iron).

1 and 2 are axles carrying on the respective ends thereof the wheels 3 and 4 upon which the frame A is mounted, said axles 1 and 2 are secured within shaft boxes 5 and 6 respectively. Above each shaft box is fitted a spiral spring 7, for the purpose of forming a cushion thereby assisting the tension device when passing over rough surfaces and yielding sufficiently to overcome such surfaces without having to regulate the tension device which would ordinarily have to be done. Secured on the axle 1, is a beveled gear 8, which intermeshes with a similar beveled gear 9, carried by shaft 10, which is secured to the frame A by means of the bearings 11 and 12. On the o )posite end of the shaft is keyed the beve ed gear 13, which intermeshes with the feathered edge of the main driving gear wheel 14, the said driving gear wheel 14 being secured on the main shaft 15, which is secured to the frame A by means of the bearings 16 and 17. Secured on the main driving wheel 14 is a handle 18. Formed on the front part of the frame A are two arms 19 and 20; 21 is a shaft secured on the arms 19 and 20 respectively by means of the bearings or shaft boxes 22 and 23. Secured on the upper end of said shaft is the beveled gear 24, which intermeshes with the main driving gear wheel 14. On the opposite end of the shaft 21 is secured another beveled gear wheel 25, which intermeshes with beveled gear 26 secured on the vertical shaft 27 said beveled gear 26 being adjustable on the said shaft 27 by reason of the key 28 and the sleeve 29. Secured on the free end of the arm 1.9 is a tension device 30, controlled by the thumb screw 31, the tension device being composed of a cap 32, inwardly screw threaded at 33, a cylinder 34, exteriorly threaded on the upper end at within the cylinder 35 is placed a spiral spring 36, above which is fitted a washer 37 countersunk at 38, into which is fitted the oval smooth end 39 of the thumb screw 31.

40 is the head formed on the shaft 27, and 41 is a collar fitted around the extended por tion of the shaft 27 and upon which rests the spring 36. Between the collar 41 and the shaft head 40, and between the shaft head 40, and the bottom portion 42 of the cylinder are placed the ball bearings 43, for the purpose of decreasing the friction on the head 40 of the shaft 27 and to insure comparatively easy rotation; the lower end portion of the shaft is secured to the frame A by means of the bearing 44.

45 is the cutter head which is provided with a threaded stem 46 and is secured on the end of the shaft 27, by means of the collar 47 which is threaded at 48 and the key 49; the collar is provided with lugs 50 and the shaft with a spanner hole 51 for the purpose of being engaged by suitable tools for removing the head. The head 45 is providedwith a series of slots 52, 53 and 54 which extend through the head and are located respectively as shown in Fig. 4, the purpose of location to be hereinafter explained.

55 is a cutter blade, secured-within the slots of the cutter head by means of the thumb screw 56.

My device is operative as follows, the main driving gear wheel 14 is driven or turned by means of hand power applied to the handle 18, by reason of the beveled gear 13 beingintermeshed with the main driving gear wheel 14, and the beveled gear 9 secured on the opposite end of the shaft 10 being intermeshed with the beveled gear 8 on the axle 1, the machine by the turning of the main driving gear wheel 14 is caused to move forward. At the same time, by reason of the gear 24 intermeshing also with the main driving gear wheel 14; power is transmitted through gear 24 to gear 25 on the end of shaft 21, which gear intermeshes with gear 26 secured on the vertical shaft 27, causing the shaft to turn and rotate the cutter head 45 secured on the lower end thereof. By reason of the location of the cutter blades in the cutter head, the entire surface equal to the radius of the cut ter head is cut or planed by each revolution of the cutter head. The cutter blades are held securely and firmly within the slots of the cutter head in the manner described and by reason of the tension device the thickness of the desired cut to be made by the cutter blades is regulated.

It will be seen that the driving wheel 14 is located parallel and adjacent to one of the sides of the frame, thus being easily manipulated by the operator walking at this side of the frame. The cutter head 45 is located at the end of the frame remote from the axle to which is geared the driving wheel, and is at the side of this end remote from the driving wheel. The disposition of the cutter head at the corner of the machine in this manner insures that the cutters will operate close to the baseboard; and therelative positions of the driving wheel and cutter head enable the operator to walk on the side of the machine which is away from the wall. As shown, it is preferred to locate the driving wheel substantially centrally of the frame from front to rear thereof; and the intermediate shaft for the axle is inclined downward from the wheel in one direction, and the intermediate shaft connecting with the cutter shaft is inclined downward from the driving wheel in the re verse direction. This second intermediate shaft is likewise given a sidewise inclination, in order to bring it into operative relation to the cutter shaft. This form of gearing is the simplest and most direct for this general type of machine, is well balanced and avoids the use of chains and belts.

The machine is made entirely of metal and is of suflicient weight to hold the cutter blades against the surface desired to be planled even when the extreme tension is app 1ec Slight changes might be resorted to in the form and arrangement of the several parts described without departing from the spirit and scope of my invention, hence I do not desire to limit myself to the exact construction as herein set forth; but,

Having described my invention what I claim as new and desire to secure by Letters Patent, is:

1. A floor planer, comprising a frame, carrying wheels therefor, an upright hand-operable driving wheel mounted on the frame parallel and adjacent to one side thereof, a horizontal rotatable cutter head disposed at the base of the frame and at one of the corners thereof pertaining to the side opposite from the driving wheel, and operative connections between said driving wheel on the one hand and the carrying wheels and the cutter head 011 the other hand.

2. A floor planer, comprising a frame, pairs of carrying wheels at the ends thereof, an axle having a bevel gear connecting the members of one pair, an upright hand-oper able driving wheel mounted on the frame parallel and adjacent to one side thereof and substantially centrally of the frames longi tudinal dimension, said driving wheel being formed as a bevel gear, an intermediate shaft mounted in boxes on the frame and inclined downward below said driving wheel, bevel gears on said shaft meshing with the driving wheel and the axle-gear respectively, a vertical cutter shaft journaled in boxes on the end of the frame remote from the geared axle and at the side of said end remote from the driving wheel, and having a bevel gear, a second intermediate shaft mounted in boxes on the frame and inclined downward and sidewise from the driving wheel, bevel gears connecting said shaft with the driving wheel and the cutter shaft gear respectively, and a horizontal cutter head carried by the lower end of the cutter shaft at the base of the frame.

3. A floor planer, comprising a frame having carrying wheels, a vertical cutter shaft mounted yieldably in the frame and carrying a horizontal cutter head at its lower end at the base of the frame, means for propelling the frame and rotating said shaft, a head on the upper portion of the shaft, an upright cylinder carried by the frame and inclosing said head, bearings between the head and the bottom of the cylinder, a collar loosely overlying said head, bearings between the head and collar, a plate screw adjustable vertically within the cylinder, and a spring between said plate and collar.

In testimony whereof I afiix my signature in presence of two witnesses.
